    Well it's been said here many a time that your service manual is your best friend.

    Try swapping plug wires to see if the trub moves. If so, check your wires. My '99 FLHR had the front plug wire go bad from pinching/vibration from the tank. Yours may be similarly pinched. If it has stock wires, an upgrade isn't a bad thing and will at least take that worry out of the troubleshooting equation.
